I have been reading all night, but I have no idea how I installed PSTRICKS to begin with. Can anyone explain how I can install PSTRICKS for Mactex. Step by step?./pstricks.tex:1: LaTeX Error: Two \documentclass or \documentstyle commands.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
l.1 \documentclass[12pt]{article}
?
